本文介绍如何在Linux系统中安装和配置MeeGo 1.1 SDK。

Contents

准备/约定

  • 硬件: 任一较新款的处理器, 比如32位的Intel Atom 或者 Intel Core 2 CPU. 为使用QEMU 需要将MeeGo运行在虚拟机中，为此你的系统必须支持虚化技术 (术语Virtualization Technology,或者说VT). 清参考图形加速获取更多信息.
  • 软件: MeeGo 1.1 SDK 已经在32位Fedora 12, [Fedora 13, Ubuntu 9.10, 和 Ubuntu 10.04 LTS进行验证. 对于其它主机操作系统的支持情况请访问this page.
  • Root 权限: 安装 SDK 需要你具备root权限. 在执行需要root权限的命令时，通常都会在命令前冠以"sudo"的前缀. 为了方便, 最好为你的登录用户增加可以执行"sudo"命令的权限，这样可以方便的在root权限和普通用户权限之间进行切换,(可参考 sudo的帮助页.)
  • 命令: 本文给出的命令例子都会以"$"指示."$"不是命令的一部分，在终端输入命令时请不要输入字符"$".

为你的发行版配置软件库安装源

针对Ubuntu或Debian平台

  1. 将下面文本行加入到/etc/apt/sources.list.d/meego-sdk.list中.
    根据你的操作系统和版本，将${distribution}/${version}替换成以下字串: "debian/5.0", "ubuntu/09.10", "ubuntu/10.04" or "ubuntu/10.10". 
    deb http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/ /
  2. 为软件仓库增加公钥: 
    $ gpg --keyserver pgpkeys.mit.edu --recv 0BC7BEC479FC1F8A
$ gpg --export --armor 0BC7BEC479FC1F8A | sudo apt-key add -
  3. 更新软件源: 
    $ sudo apt-get update
  4. 如想测试软件源是否正确被添加, 请运行以下命令测试. 正常的情况会在屏幕上打印出MADDE包的详细信息. 
    $ apt-cache policy madde

针对Fedora平台

  1. 进入yum软件源配置目录: 
    $ cd /etc/yum.repos.d/
  2. 增加MeeGo SDK的yum软件源.
    根据你的Fedora版本将下面命令中的${distribution}/${version}替换成相应的: "fedora/12" 或 "fedora/13". 
    $ sudo wget http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo
  3. 安装签名公钥: 
    $ sudo rpm --import http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/repodata/repomd.xml.key
  4. 更新软件包数据库: 
    $ sudo yum update

针对MeeGo平台

  • To add the MeeGo SDK repository on a system running MeeGo, run the following command.
    Replace ${distribution}/${version} with one of the following values: "meego/1.1" or "meego/trunk". 
    $ sudo zypper addrepo -f http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo

针对openSUSE平台

  • To add the MeeGo repository, run the following command.
    Replace ${distribution}/${version} with one of the following values: "opensuse/11.2" or "opensuse/11.3". 
    $ sudo zypper addrepo -f http://repo.meego.com/MeeGo/sdk/host/repos/${distribution}/${version}/meego-sdk.repo

安装 MeeGo SDK

  • Debian / Ubuntu 
    $ sudo apt-get install meego-sdk
  • Fedora 
    $ sudo yum install meego-sdk
  • OpenSUSE / MeeGo 
    $ sudo zypper install meego-sdk

只装ARM版本的:

  • Debian / Ubuntu 
    $ sudo apt-get install meego-sdk-armv7l
  • Fedora 
    $ sudo yum install meego-sdk-armv7l
  • OpenSUSE / MeeGo 
    $ sudo zypper install meego-sdk-armv7l

只装IA32版本的:http://wiki.meego.com/SDK/Docs/1.1/Configuring_QEMU_runtimes

  • Debian / Ubuntu 
    $ sudo apt-get install meego-sdk-ia32
  • Fedora 
    $ sudo yum install meego-sdk-ia32
  • OpenSUSE / MeeGo 
    $ sudo zypper install meego-sdk-ia32

安装MeeGo目标机交叉编译环境

所谓 目标机交叉编译环境是用于编译MeeGo程序所需要的交叉编译工具和开发库(sysroot). 下载下来后是一个很大的(大约250MB).bz2格式的文件. MADDE (MeeGo应用开发和调试环境的缩写,(background)) 是一个用于帮助下载和安装目标交叉编译环境的工具集。"mad-admin"是MADDE的一个命令行工具. 你可以安装多个目标机交叉编译环境（比如针对arm的和针对x86的）并在Qt Creator中切换它们（会在后头介绍）.

  1. Create a MeeGo target using MADDE
    Run the command below. Replace <target> with one of
    • meego-core-armv7l-1.1.2: Build applications for ARM handheld devices (such as N900)
    • meego-handset-ia32-1.1.2: Build applications for x86 handheld devices (such as Aava)
    • meego-netbook-ia32-1.1.2: Build applications for x86 netbooks.
    Note that the -f flag instructs MADDE to download the Target tarball (bz2) first. 
    $ sudo mad-admin create -f <target>

    If you encounter problems, check the Troubleshooting page

  2. To check that the target has been installed correctly, run the following.
    Replace <target> with one of the values described in the previous step 
    $ mad -t <target> pscreate -t qt-simple qthello
$ cd qthello
$ mad -t <target> qmake
$ mad -t <target> make

    Note: Running qmake will print "-unix is deprecated" This is not an error with the compilation. You can safely ignore this for now.

  3. To check that the qt-simple application is created for the correct target, run: 
    $ file build/qthello

Install MeeGo Runtime

A Runtime is the MeeGo OS image that is run with QEMU when debugging applications on your host system. It is not required if you develop against real hardware running MeeGo. It is downloaded as a large (~650MB) .bz2 file using MADDE. The Runtime is not needed until you have finished configuring Qt Creator. However, as this step may take some time, it is recommended to start it now so that it can proceed in the background while you continue following the steps on this page.

See Downloading a Runtime and Using QEMU

Configuring Qt Creator to use the MeeGo toolchain(s)

Start Qt Creator by selecting Applications > Programming > Qt Creator.

Configure Qt Creator to use the MeeGo toolchain(s):

  1. Go to Tools > Options > Qt4 > Qt Versions.
  2. On the right side of the Qt Versions view, click on the plus sign button to add a new version.
    A blank, new version appears in the Qt Versions view.
  3. On the Version Name line, specify a name for the new version.
  4. On the qmake location line, specify a qmake location for the new version. The toolchain installs by default to usr/lib/madde/linux-i686/targets/<target>/bin/qmake.
  5. Click Rebuild, Apply and OK.
Adding the MeeGo toolchain(s) in Qt Creator

Using the MeeGo SDK Qt version

It is also possible to use Qt Creator without a MeeGo toolchain. This option can be useful if you don't need to cross-compile your software: for example, if you are doing QML development with no use of C++.

The steps are the same as above, but the qmake location is set to the qmake installed with the meego-sdk-qt libraries. The usual location for this on Linux is: 

/opt/meego/meego-sdk-qt/bin/qmake

Note: On Ubuntu 10.10, you may need to install g++ in order for this step to work. If necessary, do this: 

$ sudo apt-get install g++

Developing with the SDK

To start developing with the MeeGo SDK, the hello world tutorial is a good starting point.

This tutorial covers how to start a project, package it, and deploy it to a device (either a real device, or a QEMU runtime set up through MADDE).

Removing components

On Ubuntu

To remove installed components, run: 

$ sudo apt-get remove --purge meego-sdk-qtcreator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu meego-sdk-qt

To remove dependencies related to installed components, run: 

$ sudo apt-get autoremove

To remove MADDE directory (it is not automatically removed when "madde" package is uninstalled): 

$ sudo rm -rf /usr/lib/madde

To remove the packages from your local repository (/var/cache/apt/archives/), run: 

$ sudo apt-get clean

On Fedora

To remove installed components, run: 

$ sudo yum remove meego-sdk-qt-creator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu

To remove MADDE directory: 

$ sudo rm -rf /usr/lib/madde


On openSUSE

To remove installed components, run: 

$ sudo zypper remove -u meego-sdk-qt-creator madde qt-tools arm-2009q1 qemu-arm qemu-gl meego-sdk-i586-toolchain meego-qemu

To remove MADDE directory: 

$ sudo rm -rf /usr/lib/madde
